They do not care to know how the evolutionary process is taking place, nor are they eager to know what will happen after they finish their small human life span. This is the attitude of sudras. Sri Caitanya Mahaprabhu’s mission, this Krishna consciousness movement, is trying to elevate sudras to the brahmana platform so that they will know the real goal of life.
